FS401-DI Aquarium RO Unit

Aquarium RO System with Built in Pressure Gauge and Deionization (DI) filters
Removes up to 99% of all impurities - including silicates - for a clean, clear aquarium

Aquarium RO system
Clean, pure water is a priority for all fish. No equipment is more effective in helping create ideal water conditions than Reverse Osmosis (RO) units. These units filter out up to 99% of chemicals found in tap water.
Our Aquarium RO Systems meet stringent standards. A wide variety of options ranging from economy 3-stage units to top of the line 5-stage RO/DI units are available to suit your exact needs.

Deionization (DI) filters
De-mineralize filter takes the full size RO to a higher level of filtration. It is an excellent selection for reef enthusiasts and other serious aquarists, especially those who live in areas with exceptionally high levels of phosphates in their tap water. Our unit includes: sediment pre-filters, carbon pre-filters and TFC (Thin Film Composite) membrane, Deionization (DI) post-filters in clear housings. The post deionizer takes the small percentage of contaminants that the membrane could not remove and filters this to greater than 99.99% pure. It will give you 0 ppm TDS, Conductivity attainable less than 0.1uS/cm or resistivity of close to 18 meg.ohm

Why do I need RO water?
Tap water contains impurities that cause problems when added to an aquarium. These include phosphate, nitrate, chlorine, and various heavy metals. High levels of phosphate and nitrate fuel aggressive algae growth, and copper, often present in tap water due to leaching from pipes, is highly toxic to invertebrates. Because RO filters remove practically all of these impurities, they are essential for aquarists, particularly marine hobbyists. (please click here for more information)
